Synchronization code detecting apparatus for cell search in a CDMA system

摘要

A synchronization code detecting apparatus is designed for synchronization code detection in cell search in a code division multiple access (CDMA) system. The synchronization code detecting apparatus mainly includes a compensation unit for providing frequency offset compensation to the incoming signal and for determining a plurality of sampling points of the incoming signal. A plurality of sub-detecting units is coupled to the compensation unit for detecting a synchronization code of the incoming signal transmitting from the compensation unit. A selection unit is coupled to the output of each sub-detecting unit for selecting a plurality of slot boundaries as a plurality of candidates to be forwarded to a second processing stage. Consequently, the synchronization code detecting apparatus effectively reduces the effect of clock offset in the system without increasing the hardware complexity and power consumption.
